Hello everyone, I've been trying to find this for quite a long time now, but with no luck. This story is about an artist who is obsessed with her own body, only choosing to have sex with women and men who resemble her physically. This eventually manifests itself into her reflection attacking her because the original wouldn't make the first move or something like that. It escalates to the point where any reflection of herself while she's alone, whether it's broken glass or a mirror or whatever, triggers the doppelganger. One notable scene is where the doppelganger forces the original to wear a mask (that the original would force on her lovers) as a means of self-humiliation.
Thanks in advance, folks
